Network database control device and method thereof

ABSTRACT

A network device control unit and method are provided in which, not all MIB objects under the control of the network management software are simultaneously acquired during startup of the network management software so the almost simultaneous flow of a large volume of SNMP packets in the LAN will not occur and along with a simultaneous reduction in the load on communications lines, the load on devices such as the printer and network board processing their SNMP packets will also become small. To accomplish this, windows allocated to individual network peripheral devices on a one to one basis and controlling the network device are utilized as device windows, and information to be displayed on the initial screen of the device window is acquired as the initial sheet and displayed. Device windows also acquire and display different sheet information on the device window when determined an entry has been made by the user requesting display of a different type of sheet information.

BACKGROUND OF THE INVENTION

This invention relates to a network control device and method including network control software.

In recent years local area networks (LAN) for connecting computers together have become widespread. These type of local area networks are capable of connecting computers in the same floor of a building or the entire building, a group of buildings, a district or even larger areas and can even connect to networks on a worldwide scale. Each of these mutually connected local area networks (LAN) may utilize diverse hardware connection technology or a plurality of network protocol.

Other isolated local area networks (LAN) of simple structure can be supervised by individual users. In other words, the user can replace equipment, install software and diagnose problems.

However, large-scale complex LAN and large, mutually interconnected LAN groups require management referred to here as “Management”. This “Management” means both a person to act as the network administrator and the software used by the network administrator. In this document, the term “management” signifies control utilizing software to manage the entire system, and the term “user” signifies the person utilizing the network control software. The user usually acts as the system control administrator. The user can make use of the network control software to obtain control data on the network and change this data.

Large-scale network systems are usually required to be active systems that must constantly perform equipment expansion or removal, software updating and problem detection, etc. Generally, such systems are owned by various persons or exist as various systems supplied by various operators.

Several methods have been attempted with numerous standards systems as methods for controlling devices on networks comprising a large-scale network system. The International Standards Organization (ISO) has proposed a general-purpose standards framework called the Open System connection (OSI) model. The network control protocol for the OSI model is called the Common Management Information Protocol. The Common Management Information Protocol or CMIP is a common network control protocol from Europe.

Also from the USA, a network management protocol for greater common use is known as Simple Network Management Protocol (SNMP) which is a complete change from the CMIP associated with it. (See “Introduction to TCP/IP Network Management—For Practical Network Control” by M. T. Rose, translated by Takeshi Nishida, First edition Aug. 20, 1992 Toppan.)

This Simple Network Management Protocol has at least one network management station (NMS) in the network management system. Each station has a plurality of management nodes including agents, as well as a network protocol so that the management stations and agents can exchange management information. The user can therefore obtain data on the network and also make changes to this data by utilizing electronic communication (modem) and the agent software for the management node via this network management software on NMS (network management station).

The agent here, refers to the software running as a background process of the target devices. When the user requests management data for equipment on the network, the management software places the object identification information in a management packet frame and sends this object information to the target agent. The agent interprets this object identification information, extracts data corresponding to this object identification information, places this data back in the packet and sends this packet back to the user. In some cases, a process corresponding to the data that was extracted, may be called up.

This agent also maintains data regarding its own status in a data base configuration. This data base is called a Management Information Base (MIB)). FIG. 4 shows a concept view of the MIB configuration. As shown in FIG. 4, the MIB has a tree type data structure and all nodes are affixed with a number. The number inside the parentheses in FIG. 4 is an identifier for that node. For instance, the identifier for node 401 is “1”. The identifier for node 402 is a “3” under node 401 and therefore listed as “1·3”. In the same way, the identifier for node 403 is listed as “1·3·6·1·2”. The identifier for these nodes is known as the object identifier.

The structure of this MIB is called the Structure of Management Information (SMI) and conforms to the “RC1155 Structure and Identification of Management Information for TCP/IP-based Internets”.

Only a fraction of the MIB specified as a standard has been extracted and shown in FIG. 4.

In FIG. 4, the numeral 404 is a node representing the peak of the object group and referred to as a standard MIB provided as a standard feature in equipment managed by Simple Network Management Protocol (SNMP). The detailed structure of the objects ranked below this node are specified in “RFC1213 Management Information Base for Network Management of TCP/IP-based internets: MIB-II. The numeral 405 is a node at the peak of the object group called the printer MIB and is provided as a standard item in printers managed by Simple Network Management Protocol (SNMP). The detailed structure of the objects ranked below this node are specified in “RFC1759 Printer MIB. Further, the numeral 406 is referred to as a private MIB and is a peak node for defining autonomous MIB such as used by companies and organizations. The numeral 407 is called a company expansion MIB and is a peak node for autonomous expansion of a company within the private MIB. The Canon Corporation has been assigned “1602” as a company number for definition as an autonomous entity and the peak node 408 for defining Canon MIB which is a Canon autonomous MIB and “408” is ranked at a position below the node 407 which signifies companies. The object identifier “1·3·6·1·4·1·1602” is for the peak node of the Canon MIB.

However, on starting up the network management software, and acquiring all the MIB-objects controlled by the network management software, a massive quantity of SNMP packets flow through the LAN at nearly the same time. This flow places a large burden on the channels and at the same time also places an extremely heavy load on the printer and the network boards that process those SNMP packets.

Also, along with this increased load, the startup of the network management software also requires more time (initial menu display) which causes the user to feel stressed.

Further, the network printer management software is constantly writing the MIB data with the same process sequence. Therefore, when the user directs the network printer software to write MIB data, the network printer software of the conventional art constantly writes all of the directed MIB data. However writing all of the MIB data each time is not always necessary and the process is redundant. In other words, the network printer software generally displays a plurality of information for the user simultaneously (information matching the MIB data) and even if the user only rewrites just a fraction of all this information, all of the displayed information of the overwrite is processed as items specified by the user.

Among the MIB data specified for rewriting by the user, items for which write is requested from the network management software for SNMP agents on the network printer, represent only the MIB data actually rewritten by the user. There is therefore no need to request write via SNMP agents on the network printer of MIB data which the user has not rewritten. Not only is such writing unnecessary but reducing the quantity of MIB data subject to write request via SNMP agents on the network printer from the network printer management software is also essential in order to reduce the load (amount of work) assigned to the network traffic (data quantity) and the network printer.

SUMMARY OF THE INVENTION

In view of the above circumstances, it is therefore an object of this invention to provide a network data base control device and method thereof which does not simultaneously acquire all MIB object information controlled by the network management software and therefore will have no simultaneous flow of a large volume of SNMP packets, and along with reducing the load on the device channels, the load on devices such as the printer which process the SNMP packets and load on the network board will be small.

A further object is to provide a network data base control device and method thereof wherein, by making the load on the LAN, printer and network boards small, the time required to start up (display initial menu) the network management software will be shortened and the user will thus be provided with an easier operating environment.

Still another object is to provide a network data base control device and method thereof wherein, in network printer management software utilizing the SNMP protocol, no processing change or write requests are made for unnecessary MIB data, while write requests for necessary MIB data for SNMP agents of the device (such as printers) on the network matching write-specified information from the user will be processed, thus allowing the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

In order to achieve the above objects, the network device control method of this invention is provided with the following configuration. Namely, a network device control method having;

an initial sheet information acquisition and display step for acquiring and displaying initial sheet information on the initial menu of a device window and the device window is a window for managing and controlling a network device and applicable windows are assigned one each to each network peripheral device and,

Yet still, the network device control method of this invention, also comprised of the following process steps in a network device control method utilizing SNMP protocol and characterized by having a step to identify write requests for unnecessary MIB data and write requests for necessary MIB data in SNMP agents of the network device within MIB data corresponding to write information specified by the user.

Further, in accordance with the preferred embodiment of this invention; provision of a step to store MIB data loaded from the MIB data read-out process into the NIB data cache; and a step to compare MIB data corresponding to write information specified from the user in the MIB data write process versus data stored in the MIB data cache in the aforementioned step, in order to be able to identify write requests for necessary MIB data and write requests for unnecessary MIB data from among the MIB data matching write information specified from the user in SNMP agents of the network printer.

Alternatively, provision of a step to store data written in the MIB data write process into the MIB data cache; and a step to compare MIB data corresponding to write information specified from the user in the MIB data write process versus data stored in the MIB data cache in the aforementioned step, in order to be able to identify write requests for necessary MIB data and write requests for unnecessary MIB data from among the MIB data matching write information specified from the user in SNMP agents of the network printer.

Or still further, provision of a step to store MIB data loaded from the MIB data read-out process into the MIB data cache; a step to store data written in the MIB data write process into the MIB data cache; and a step to compare MIB data corresponding to write information specified from the user in the MIB data write process versus with MIB data stored in the MIB data cache in either of the steps, in order to be able to identify write requests for necessary MIB data and write requests for unnecessary MIB data from among the MIB data matching write information specified from the user in SNMP agents of the network printer.

This invention also is capable of reducing the network traffic (data volume) and reducing the load (work load) applied to the network printer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereafter, the embodiment of the invention will be described while referring to the accompanying drawings.

A large-scale network requiring management by the embodiment of this invention will first be described.

FIG. 1 shows a network board (NB) for connecting the printer to the network, connected to a printer 102 having an open-style architecture. The NB101 is connected to the local area network (LAN) 100 by for instance an LAN interface such as Ethernet interface 10Base-2 having a coaxial connector or 10 Base-T having RJ-45.

A plurality of personal computers (PC) such as a PC103 or PC104 are also connected to the LAN 100. The PC103 and PC104 can communicate with NB101 within the network operating system. One personal computer such as the PC103 can be directed to function as the network controller. Also, a printer 105 connected to the PC104 can be connected to the PC103.

A file server 106 is connected to the LAN 100. This file server 106 controls access to files stored in a large-capacity (for example 10 billion byte) network disk 107. A printer server 108 performs printer on the connected printers 109 a, 109 b or with printer 105 in a remote location, etc. Other peripheral equipment not shown in the drawing may also be connected to the LAN100.

More specifically, the network shown in FIG. 1 can utilize network software such as Novell or Unix software for achieving efficient communications between the various network members. Any network software is capable of being used such as NetWare (commercial trademark of the Novell Company, omitted hereafter). A detailed explanation relating to this software package may be found by referring to the on-line documentation enclosed with the NetWare package. This explanation can also be purchased along with the NetWare package from the Novell Company.

In a simplified description of the layout of FIG. 1, a file server 106 fulfills the function of file manager for receiving data files, storing, queueing, caching and transmission of data files with the LAN members. For instance, files made on the PC103 and PC104 are respectively sent to the file server 106 which sorts these files in order, and in compliance with commands from the print server 108, sends these ordered data files to the printer 109 a.

The data files created on the PC103 and PC104 are sent to the LAN100 and files received from the LAN100 or such kind of files are labeled and processed on a computer conFig.d to perform such tasks. The computer equipment is shown in FIG. 1, however other computer equipment suitable for running the network software may also be included. For instance, when using UNIX software, a UNIX workstation can be incorporated into the network and under appropriate conditions, can be used along with the computers shown in the Fig.

Usually, a local area network such as the LAN100 provides services to a certain number of local user groups such as on one floor of a building, or a plurality of connected floors in a building. For instance, a wide area network (WAN) can be formed to handle users isolated from other users such as users in other buildings or in other prefectures, etc. The WAN is fundamentally an aggregate consisting of high-speed digital lines such as telephones lines of high-speed digital networks (ISDN) to connect a plurality of LAN. Accordingly, as shown in FIG. 1, the LAN100, LAN110 and LAN120 form WAN connected by modulators/demodulators (modem) and a transponder 130 and a backbone 140. These are simple electrical connections implemented by several bus lines. Each LAN incorporates a custom personal computer. Though not always needed, a file server and a print server are normally incorporated into the LAN.

Therefore, as shown in FIG. 1, the LAN110 incorporates a PC111, a PC112, a file server 113, a network disk 114, a print server 115, a printer 116 and a printer 117. In contrast, the LAN120 incorporates only a PC121 and PC122. The equipment connected with the LAN100, LAN110 and LAN120 can access other LAN equipment functions by means of WAN connections.

Installing Agents on Network Boards

Agents are installed on network boards for connecting the printer to the network. This process allows the printer to be controlled by the network management software. The user can acquire or change the status of the information for the printer subject to control by the network control software. More specifically for instance, the characters shown on the liquid crystal display of a printer can be acquired or the default paper feed cassette changed. Hereafter, a sample connection to a printer, of a network board (NB) mounted with an agent will be described.

As shown in FIG. 2, the NB101 is preferably mounted in the internal expansion slot of the printer 102. The NB101 becomes a “built-in” network node having a data storage function and performing the processing shown below. The structure of this NB101 has the merit of possessing special auxiliary functions for integrating and controlling a large multi-area WAN network. These auxiliary functions for instance, include printer control and status monitoring of remote network locations (for instance offices of network coordinators) and automatic control and printer load characteristics of the printer for providing a guaranteed initial printer environment for the next printer user once the current printing job is finished or may include access through the network for setting a schedule for toner cartridge replacement and incorporating a printer log or statistical records.

An essential element in this NB design is the function for accessing printer control status from NB101 by way of a two-way interface such as the shared memory 200. Besides this shared (or joint) memory, an interface such as an SCSI interface can also be used. Thus, print operation information for a plurality of convenient auxiliary function programs can be sent to the NB101 or to external network nodes. The print image data and control information blocks are formed by a microprocessor 301 on the NB101, listed in the shared memory 200 and then loaded into the printer 102. At the same time, the printer status information is sent from the printer 102 to the shared memory 200 and then loaded by means of the microprocessor 301 on the NB.

FIG. 2 shows a fragmentary view of the NB101 installed in the printer 102. As shown in FIG. 2, the NB101 is comprised of a print circuit board 101 a installed on a faceplate 101 b for making the network connection and connected to the printer interface card 150 by means of the connector 17. The printer interface card 150 directly controls the printer engine of the printer 102. The printing data and the printer commands are input to the printer interface card 150 by way of the connector 170 from the NB101, while the printer status information is acquired by way of the connector 170 from the printer interface card 170. The NB101 communicates this information to the LAN100 by way of the network connector of the faceplate 101 b. At the same time, the printer 102 can also receive printing data from the serial port 102 a and the parallel port 102 b, etc.

FIG. 3 is a block diagram showing the electrical connections of the NB101, the printer 102 and the LAN100. The NB101 is directly to the LAN100 byway of the LAN interface and connected by way of the printer interface card 150 to the printer 102. The NB101 is comprised of a microprocessor 301 to control the NB101, a ROM 303 to store the operating program for the microprocessor 301, a RAM 302 for utilizing the program run by the microprocessor 301 as work, and a shared memory 200 for exchanging data between the NB101 and the printer interface card 150 and these various components are mutually connected by internal buses. The program used by the NB101 for operating the SNMP agent is stored in the ROM303. The microprocessor 301 performs operation in compliance with the program stored in the ROM303 and utilizes the RAM 302 as the work area. The shared memory 200 is utilized as the buffer zone for communication with printer interface card 150.

The microprocessor 151 on the printer interface card 150 performs data access with the NB101 by way of the shared memory 200 installed in the NB101. The microprocessor 151 of the printer interface card 150 also performs communication with the printer engine 160 for actually moving the printer mechanism.

PC Configuration

The configuration of the personal computer operating the network management software is described as follows.

FIG. 5 is a block diagram showing the configuration of the PC capable of being operated by the network management software.

The reference numeral 500 in FIG. 5 denotes the PC operated by the network management software and is equivalent to numeral 103 in FIG. 1. The PC500 is controlled by a network management program executed by a CPU501 supplied with the program from a floppy disk drive (FD) 512 or stored in a ROM 502 or in a hard disk (HD) 511. Devices connected to the system through the system bus 504 are driven by this network management program in a coordinated manner. The numeral 503 is a RAM which functions as the main memory of CPU 501 or the work area and the like. The numeral 505 denotes a keyboard (KBC) controller for performing control via instructional inputs from a keyboard (KB) 509 and a pointing device not shown in the Fig. The numeral 506 is a CRT controller (CRTC) which controls the display on the CRT (510). The numeral 507 denotes a disk controller (DKC) which controls access with a floppy disk controller (FD) 512 and a hard disk (HD) 511 for storing boot programs, various applications, edit files, user files and network management programs, etc. The numeral 508 denotes a network interface card (NIC) which performs two-way data exchanges between the agent or the network equipment by way of the LAN100.

One example of a read-out/write method for the MIB data of the network printer management software will be explained while referring to FIGS. 159 and 160.

The start of MIB data readout is shown in Step S15900.

In Step S15901, the MIB data readout request is performed for the network printer management software from the SNMP agent of the network printer.

Then in Step S15902, the requested MIB data for the network printer management software from the SNMP agent of the network printer is read-out and reported.

Finally, in Step S15903 the process in FIG. 159 ends.

Next, the MIB data write method in the network printer management software will be explained while referring to the flowchart in FIG. 160.

The start of MIB data write is shown in Step S16000.

In Step S16001, the MIB data write request is performed for the network printer management software from the SNMP agent of the network printer.

Then in Step S16002, the requested MIB data for the network printer management software from the SNMP agent of the network printer is written and reported.

Finally, in Step S16003 the process in FIG. 160 ends.

However, in writing of MIB data as stated previously, all of the specified MIB data is written and on some occasions, unnecessary data is also written so that a large load is applied in terms of network traffic volume and network printer work.

Whereupon, this invention resolves this problem by controlling operation so that only necessary MIB data is changed.

Next, in a large-scale network system such as shown in FIG. 1, a more detailed explanation is given for cases where network management software operated by a personal computer (hereafter PC) is controlling a device (such as a printer) subject to network management.

FIG. 150 shows the operation when the user starts the network management software and the network management software operation is performed when the desired printer is selected.

First of all, the “START” button is clicked on Windows95 (operating system from Microsoft-USA, hereafter omitted) and after selecting “Select and Run File Name”, when the file name is chosen and the network management software starts up, a list of all the MIB objects controlled by the network management software is made in Step S15001.

Step S15002 determines if all acquisition of all the object information for the list made in Step S15001 is now complete.

If acquisition of all the object information is complete, then the initial menu of this network management software is displayed and this flowchart ended by means of Step S15003.

If however, acquisition of all the object information in Step S15002 is not complete, then Step S15100 cause the process to return to printer information acquisition in Step S15002.

Step S15100 is explained in detail while referring to FIG. 151.

First, in Step S15101 an inquiry utilizing the SNMP is made to the printer and network board of a portion of the items on the MIB object list made in Step S15001. Upon which, the value of the MIB object list for which inquiry was made, is returned by the SNMP to the network management software operated on the PC.

Step S15102 determines if the SNMP communication is being performed correctly. If communication is not being performed correctly an MIB object inquiry is again made to the printer and the network board utilizing the SNMP. If communication is correct, then the process in this flowchart ends.

However, even with the above process, when all the MIB objects controlled by the network management software are acquired, a massive amount of SNMP packets flow through the LAN. Investigation has found that along with a large load placed on the channels, an extremely large load is also placed on the printer and network boards which process these SNMP packets.

In this embodiment therefore, all the MIB objects controlled by this network management software are not acquired. Consequently, there is no simultaneous heavy flow of SNMP packets through the LAN, and along with reducing the load on the channels, the load placed on the printer and network boards which process these SNMP packets is also reduced.

Network Management Software Modular Structure

The configuration of the network management structure will next be described.

The network control device of this embodiment is attained by a PC conFig.d as shown for a network control unit in FIG. 5. The hard disk (HD) 511 stores the network management program performing the main operation of this embodiment as is described later on. In all explanations related from hereon, the CPU501 will serve as the main element of the hardware unless otherwise stated. However, the main item in software control is the network management software stored in the hard disk (HD) 511. The operating system (OS) of this embodiment is assumed to be Windows95 (Microsoft) however the OS need not be restricted to Windows95. The network management program relating to this embodiment may be provided in a form stored on a recording medium such as floppy disks or a CD-ROM, etc. In such a case, a floppy disk controller (FD) 512 such as shown in FIG. 5 or a CD-ROM drive not shown in the drawing may be utilized to load the program from the recording medium and install the program in the hard disk (HD) 511.

FIG. 6 is a block diagram view of a modular structure of the network management software relating to the embodiment of this invention. This network management software is stored in the hard disk 511 of FIG. 5 and the software is run by means of the CPU501. In such cases, the CPU501 uses the RAM 503 as the work area.

The numeral 601 in FIG. 6 denotes the device list module which is a module for displaying on a list, all the devices connected to the network (this list is given in more detail in FIG. 15 as explained later). The numeral 602 denotes the overall control module which serves to coordinate the other modules based on instructions from the device list. The numeral 603 denotes the configurator which is the module that performs special processing relating to network settings for the agent. The numeral 604 denotes the search module which searches for a device connected to the network. Devices that the module 604 searches for are displayed on a device list 601. The numeral 605 is a network job module for acquiring print job status from the network server by utilizing the NetWare API616. (For details on NetWare API refer for instance, to the “NetWare Programmer's Guide for C” issued by the Novell Company. This text may be purchased from the Novell Company.) The numerals 606 and 607 denote the UI module for displaying the device window as related later. A UI module is provided for each model displaying detailed information. The numerals 608 and 609 denote the control modules which handle special control of models acquiring detailed information. These control modules, just as with the control modules are provided for each model displaying detailed information. The control A module 608 and the control B module 609 acquire MIB data from the device subject to net control by utilizing the MIB module 610 and then convey this data to the corresponding UI A module 606 or the UI B module 607.

An MIB module 601 performs object identifier and object key conversions. Here, the object key is a 32 bit integer matching the object identifier in a one to one relationship. The object identifier is an identifier of variable length. This variable object identifier is difficult to handle when installed as is in the network management software so the network management software of this document utilizes an object identifier and fixed length identifier internally in a one to one relationship. The host module for the MIB module 610 handles the MIB information utilizing this object key and this arrangement allows easy use in the network management software.

The numeral 611 denotes the SNMP module for sending and receiving the SNMP packet. The numeral 612 denotes the shared transport module that absorbs differences in lower ranked (downstream) protocol for transporting the SNMP data. During actual operation, the IPX handler 613 or the UDP handler 614 has the role of transporting the data. The UDP handler utilizes WinSock 617 for installation. (Refer to specifications for instance for Windows Socket API v1.1 for details on WinSock. This document can be procured from a plurality of locations and comes enclosed with Visual C++ a compiler of the Microsoft Corporation.) The numeral 615 denotes the current protocol utilized by the configurator 603 and during operation shows either the IPX protocol or the UDP protocol selected by the user. In the following explanation, the network management software of this document is called “NetSpot” (A commercial trademark of the Canon Corporation.)

NetSpot Install

The files required for install of NetSpot are usually taken from a recording medium such as a floppy disk (FD) or a CD-ROM or else may be transferred by way of the network. After the user has obtained the files needed for NetSpot install by one of these methods, the NetSpot install is commenced in compliance with the specified install procedure. This NetSpot install procedure is similar to other general software installation procedures. Namely, in that the user starts up the NetSpot installer on the personal computer (PC) and the installer then automatically performs the install. The installer copies the necessary files from the hard disk of the PC and when needed also has the user input required information so that the necessary files for NetSpot operation are edited or created.

The information entered by the user during this NetSpot install includes selection of the following two types of operating modes (controller mode (administrator mode) and general user mode).

NetSpot Operating Mode

NetSpot has the following two types of operating modes; a controller mode and a general user mode. One of these two modes is specified. Basically, the NetSpot install must be corrected in order to change the NetSpot operating mode.

Controller Mode (Administrator Mode): A mode utilized by users have specially designated rights (for instance, the network administrator or network peripheral equipment administrator).

General User Mode (User Mode): A mode utilized by a general user having no specially designated rights.

Functions that support the general user mode are functions supported with limits applied in the controller mode. In other words, the functions supported in the general user mode are equivalent to a portion of the functions supported in the controller mode.

A list of functions supported by NetSpot are related below for both the controller mode and the general user mode.

NetSpot Start-Up and Password Approval

When NetSpot is installed in the general user mode, the user can start NetSpot just by executing the NetSpot file. However, when NetSpot is installed in the controller mode, entry of the NetSpot password is requested after the user executes the NetSpot file. The NetSpot cannot start at this time in controller mode, unless the user enters the correct password. In NetSpot controller mode, the user can make all types of network peripheral equipment (device) settings. A mistake in these settings can cause misoperation or equipment breakdowns. So during startup in controller mode in NetSpot, the user is requested to enter the NetSpot password in order to prevent using controller mode by the general user. However, when entry of the NetSpot password is requested, the user can start up NetSpot in the general user mode without entering the password. This process is described in detail later on in the description of the NetSpot password entry dialog box (FIG. 10).

During install of NetSpot in controller mode, the user performing the install can set the NetSpot password during controller mode startup.

Further, after the user has started up NetSpot in controller mode, the NetSpot password can be set or changed at controller mode startup. Details are related later on, in the explanation of the NetSpot password change dialog box (FIG. 38).

The NetSpot password which has been set or changed is used from the next time NetSpot is started in controller mode. NetSpot controller mode will start if the NetSpot password entered during controller mode startup matches the actual entry but will not start if the two passwords do not match.

In NetSpot controller mode, instead of requesting the NetSpot password from the user during start-up, a check can be made in the NetWare file server for log-in by the administrator. In other words, during start-up in NetSpot controller mode, the request for entry of the NetSpot can be omitted if the user has previously logged-in to the NetWare file server as the administrator.

In actual network operation, there may be a plurality of administrators in one network environment and the administrator may vary with each piece of network peripheral equipment (device). So in NetSpot controller mode, a device password can be set as an option for each network interface board, in addition to the NetSpot password during start-up of the controller mode. This allows approval of a device password for each piece of network peripheral equipment selected by the user from the device list display window (FIG. 15) described later on.

The controller can set a device password as needed for each network interface board during selection of network peripheral equipment. When a device password has been set in the network interface board, at the time of new selection of network peripheral equipment by the user in NetSpot controller mode from the device list display window (FIG. 15) or in other words when the device window has been opened again, the device password set by the controller for each network interface board is approved.

Entry of the device password during new selection of network peripheral equipment from the device list display window in the NetSpot controller mode can be omitted if the user sets the NetSpot password during controller mode start-up as equivalent to the device password at the time of network peripheral equipment selection.

This process is related more specifically, in the explanation for the device password entry dialog box (FIG. 50) and the device password change dialog box (FIG. 137).

In password approval as described above, approval of the device password during the latter selection of network peripheral equipment is performed by implementing the Canon MIB for the network interface board so this function is not supported for network interface boards not implementing the Canon MIB.

NetSpot Exclusive Control

A conflict may possible occur between the network peripheral equipment (device) settings and the network settings, when a plurality of NetSpot controller modes are started up for one piece of network peripheral equipment. Therefore, the number of NetSpot controller modes that can be started versus one piece of peripheral equipment are restricted to one mode. In other words, the same piece of network peripheral equipment cannot be selected by a plurality of NetSpot controller modes. In contrast, a plurality of general user modes can be started for one piece of network peripheral equipment. In other words, the same piece of network peripheral equipment can be selected on more than one NetSpot general user mode.

In the exclusive control in the type of controller mode related above, the network interface boards are implemented by a Canon MIB so this exclusive control function is not supported on network interface boards not implemented by a Canon MIB. When exclusive control is not implemented then network peripheral equipment on the same network can be selected by more than one NetSpot controller mode just the same as in the NetSpot general user mode.

An illustration demonstrating the concept of exclusive control in the controller mode is shown in FIG. 9.

Transition Chart of Windows displayed by NetSpot FIGS. 7 and 8 are window transition drawings showing in sequence the NetSpot changes in response to user instructions when the user has started NetSpot in controller mode. However, the windows shown in FIG. 7 and FIG. 8 do not represent all the windows that NetSpot displays. Even when NetSpot receives no instructions from the user, all types of windows are automatically displayed according to the NetSpot operating status and information acquired from the network. These windows are however explained later on so a description is omitted here. A screen transition view of NetSpot when started in general user mode is omitted and fractional views are shown respectively in FIGS. 7 and 8.

The user can monitor the network peripheral equipment status (device) by viewing the information displayed on the respective window shown by NetSpot and can set a suitable value in these windows in order to control the network peripheral equipment (device).

When NetSpot is started in controller mode a list on a dialog box as shown in FIG. 7 is called up from each sheet related later on.

The numeral 701 in FIG. 7 denotes the device window shown in FIG. 43. This window 701 has four sheets consisting of a status sheet 702 shown in FIG. 54, a job sheet 703 shown in FIG. 100, an information sheet 704 shown in FIG. 102 and a network sheet 705 shown in FIG. 104.

Here, from status sheet 702, is the error information display dialog box 706 shown in FIG. 55, and the printer environmental setting dialog box 709 shown in FIG. 143. The printer paper eject select dialog box 707 shown in FIG. 57 is selected from this error information display dialog box 706.

The ESC/P print environment expansion 1 set dialog box 723 shown in FIG. 91, the ESC/P print environment expansion 2 set dialog box 724 shown in FIG. 94 and the ESC/P utility dialog box 725 shown in FIG. 98 are called up from the ESC/P print environment basic setting sheet 722.

Next, the printer queue set dialog box 726 shown in FIG. 10 is called up from the job sheet 703, the NetWare dialog box 727 shown in FIG. 34 is called up from the printer queue set dialog box 726. The controller information dialog box 728 shown in FIG. 103 is called up from the information sheet 704. Finally, the protocol set dialog box 729 shown in FIG. 144 is called up from the network sheet 705.

The protocol set dialog box 729 contains the three sheets consisting of the NetWare setting sheet 730 shown in FIG. 105, the TCP/IP set sheet shown in FIG. 114 and the AppleTalk set sheet 733 shown in FIG. 120. The NetWare dialog box 727 shown in FIG. 34 is called up from the NetWare set sheet 730. The description for the device list window 801 is associated with the description for FIG. 8 and so is apportioned here.

FIG. 8 is a block diagram showing the list of dialog boxes called up from the menus related later, when the NetSpot is started in controller mode.

The numeral 801 in FIG. 8 denotes the device list window shown in FIG. 15. The device list window 801 contains four menus consisting of the device menu 802, display menu 803, setting menu 804 and help menu 805. Among these, the new window device dialog box 806 shown in FIG. 22, the (standard) printer driver install window 807 in the operating system is called up from the device menu 802. Next, the display option dialog box 808 shown in FIG. 29 is called up from the display menu 803. Further, the device search range dialog box 809 shown in FIG. 30, the device display setting dialog box 810 shown in FIG. 31, the device list auto change setting dialog box 811 shown in FIG. 32, the NetWare log-in dialog box 727 shown in FIG. 34, the NetWare log-out dialog box 813 shown in FIG. 36, and the NetSpot password change dialog box 814 for changing the password utilized in running the NetSpot shown in FIG. 38 are called up from the setting menu 804. Finally, the help file window 815 showing the NetSpot help, the NetSpot version information dialog box 816 for displaying the NetSpot version shown in FIG. 42 are called up from the help menu 805.

Next, the menu for the device window 701 explained in FIG. 7 is described.

The device window 701 contains the five menus consisting of: the device menu 817, the display menu 819, the set menu 820, the test menu 821, and the help menu 822.

[OK] button: The user selects this item to validate the settings and close the dialog box.

[Device Window (See FIG. 43)]

The user double-clicks an icon displayed on the device list window (FIG. 15) to display the Device Window Dialog Box shown in FIG. 43. The number of device windows (FIG. 43) that can be opened by the user is limited to one for each device. The user clicks the tabs ([Status] [Job] [Info] and [Network] on the left side of the Device Window (FIG. 43) to move the sheet for each tab to the leading edge of the Device Window (FIG. 43).

Hereafter, the process from selecting the device from a Device List Window 801 (FIG. 15) and displaying a device window 701 (FIG. 43) is described while referring to the flowchart.

First Embodiment

Next, a first embodiment for display that will not cause the user stress is explained from the device list window 801 to the device window 701.

In FIG. 152, the flowchart shows the device window display operation for the network controller software (NetSpot) that the user is currently starting up.

The NetSpot program executed according to this flowchart is stored in a hard disk (HD) 511. A CPU501 is the main hardware element in running this NetSpot program. However, the main control element for the software is the NetSpot stored in the hard disk(HD) 511. In this embodiment, the operating system (OS) is assumed to be Windows95 however the OS is not limited to this.

A device window 701 shown in FIG. 7 opens when the user double-clicks the icon showing the device in Step S15201 in the NetSpot program. This device window 701 is shown on the CRT display of CRT 510 by ways of the CRT controller 506 by way of the PC500. However, at the completion of Step 15201, only the device window frame and the sheets for the status, job, information and network are displayed and there is no display of printer information on a sheet as shown in FIG. 43.

Next, in Step S15300, the initially displayed sheet information is acquired and shown.

Executing NetSpot in this step, completes acquisition of printer information on the initially displayed sheet in the device window 701 and as shown in FIG. 43, a display of the printer information on a sheet is possible. In FIG. 43, an example of the sheet showing the initial status sheet is shown but the job sheet, information sheet or network sheet may be shown. However, the job sheet as related later on, is provided by utilizing the NetWare service so that when acquiring printer information by means of the Step S15300, SNMP is not used.

The latter process of this step is explained in detail next.

When Step S15300 is executed and the initial sheet of the device window 701 is displayed, NetSpot implements Step S15202 and monitoring is performed to determine whether there was a request from the user to close the device window 701.

Here, if the user selects “Close” from the device menu 817 of FIG. 8, when the user clicks the X mark at the upper right of the device window 701 of FIG. 43; NetSpot closes the device window 701 by means of Step S15204 and the flowchart then ends.

If the user does not perform the operation needed to close the device window 701, then the process moves to Step S15204.

In Step S15204, NetSpot performs monitoring to check for a request from the user to select a new (separate) sheet.

Here, if the user selects [Status] [Job] [Info] [Network] from the displayed menu 819 in FIG. 8, when one of the tabs ([Status] [Job] [Info] [Network]) is clicked on the device window 701 of FIG. 43, then NetSpot implements the Step S15400 and newly selected sheet information is acquired and displayed.

If, the user did not select a new sheet, the CPU returns control to the Step S15202 and control of the process as described above is repeated.

The above explanation and flowchart described display of the device window 701 by means of the user selecting a device from the device list window 801; and if no longer needed, closing the device window 701.

Next, the operation of the Step S15300 is described by utilizing the flowchart in FIG. 153.

In this flowchart, the process for acquiring and displaying the sheet for initial display is shown.

First of all, in Step S1530 the sheet for initial display is specified. This step utilizes a status sheet 702 as the sheet for initial display but in NetSpot any of the [Status] [Job] [Info] [Network] sheets can be specified for initial display.

Here, a variety of methods are available for specifying the first sheet for display from among the above mentioned four types of sheets.

These methods are listed below.

(1) Incorporating specification of initial file into the NetSpot program beforehand.

(2) The user specifies the initial file. NetSpot acquires the sheet name for initial display from the prior initialization file at program execution.

(3) The sheet name last displayed when NetSpot was previously used is retained in the prior initialization (reset) file. Next, the sheet name for initial display is acquired from the prior initialization (reset) file at execution of the NetSpot program.

(4) An item such as “Initialize display sheet select window” is displayed at execution of the NetSpot program and the user then specifies the initialization (reset) display sheet.

(5) More than one MIB object are acquired beforehand, and when a problem object is discovered, the information for that object is set as the sheet for initial display.

After determining the sheet for initial display by means of the Step S15301, NetSpot forms a list of MIB object required for display of the sheet by means of the Step S15302. Hereafter, this sheet is called the Sheet Information List.

Finally, NetSpot implements the Step S15500 and the process of this flowchart ends.

Next, the operation of the Step S15400 is described while referring to the flowchart in FIG. 154.

This flowchart performs the acquisition and display of newly selected sheet information by the user.

First of all, in the Step S15401, NetSpot determines again the sheet for display in accordance with the user's entry. Here, as the user entry, selection of the [Status] [Job] [Info] [Network] from the display menu of FIG. 8 or clicking of a tab of tabs ([Status] [Job] [Info] [Network]) at the left side of the device window 701 of FIG. 43.

After determining the sheet for initial display by means of the Step S15401, NetSpot forms the Sheet Information List by means of the Step S15402.

Finally, NetSpot implements the Step S15500 and the process of this flowchart ends.

Next, the operation of the Step S15500 is described while referring to the flowchart in FIG. 155.

This flowchart is a modified version of the flowchart in FIG. 2 so aside from the operation for acquisition of printer information, timer processing for auto change, and cache processing for improving image display speed are utilized.

First of all, whether or not to automatically acquire sheet information is determined in the Step S15501.

Here, “Auto Acquisition” is the process for acquiring printer information by means of SNMP without using the cache related later.

The criteria for performing auto acquisition or not is “Is this first time for this sheet” in the Step S15501. NetSpot erects a “Display Over” flag for a sheet that has been opened once so the criteria in the Step S15501 is whether the “Display Over” flag has been erected or not.

If auto acquisition is not performed in the Step S15501 (in other words if the “Display Over” flag has been erected) then the process proceeds to the Step S15600.

The operation of the Step S15600 is described while referring to the flowchart of FIG. 156.

First of all, in the Step S15601, whether to examine all the Sheet Information Lists or not is determined.

At this point, if an examination of all elements of the Sheet Information list is finished, then the process of this flowchart ends.

The process then proceeds to Step S15602 if examination of all elements is not finished.

In the Step S15602 whether or not the elements of the cache values currently being examined on the sheet information list are valid is checked.

This “Cache value” is explained later on while referring to FIG. 155.

If the cache value is not valid, the process returns to Step S15601 with no other processing performed.

If the cache value is valid, then NetSpot displays the cache value with device window 701 in Step S15603.

Next, in Step 15604, after acquiring the acquisition status of elements in the above Step 15603, the process returns to Step 15601.

The explanation of the Step S15600 is now complete.

NetSpot implements Step S15502 when “YES” is selected in Step S15501 if the above Step S15600 is complete.

In Step S15502, NetSpot determines whether or not acquisition of any elements is not complete in the sheet information list.

If some elements are present whose acquisition is not complete, the printer information is acquired by means of the previously related Step S15100.

Next, in the Step S15503, a check is made as to whether or not the information acquired in the above Step S15100 is already retained as a cache value in the RAM503 of FIG. 5.

Here, “cache” refers to printer information items acquired at least once and held in the RAM503 of FIG. 5. The “cache value” is that value.

Utilizing the “cache” allows the load on the printer 102, the network board 102 and the LAN100 to be held to a minimum amount.

If the cache value is not held in the RAM503 in the Step S15503, then the process proceeds to the Step S15505.

If the cache value is held in the RAM503 in the Step S15503, then the process proceeds to the Step S15504.

In Step S15504, a check is made as to whether the value of the information acquired in Step S15100 is the same as the cache value held in the RAM503.

If, in Step S15100, the value of the information acquired in Step S15100 is the same as the cache value held in the RAM503, then the process proceeds to Step 15506.

If, however in Step S15100, the value of the information acquired in Step S15100 is different from the cache value held in the RAM503, then the process proceeds to Step 15505.

In Step S1505, NetSpot retains the information acquired in the Step S15100 as a new cache value in the RAM503.

Next, in Step S15506, the cache value retained in the RAM503 is displayed on the device window 701. The display is shown on the CRT510 by way of the CRT controller 506 of FIG. 5.

When the Step S15506 ends, NetSpot implements Step S15507.

In Step S15507, acquisition of currently processed element from the sheet information list is completed.

In the above explanation, the RAM503 was set at the location to retain the cache however this location can be substituted with the HD511.

When Step S15507 ends, NetSpot returns to Step 15502 and Steps S15502 through Steps S15507 repeat until all information from the sheet information list is acquired.

In Step S15502, if all element from the sheet information list are acquired, then NetSpot implements Step 15508.

In Step S15508, the printer status which occasionally changes over time is monitored and a decision made whether or not to automatically update the currently specified sheet information.

A plurality of methods are available for specifying whether or not to automatically update sheet information, two are listed below as examples.

(1) Set whether or not to automatically update, into the NetSpot program beforehand.

(2) The user specifies with the initialize file whether or not to automatically update sheet information. During program execution, NetSpot acquires information as to whether or not to automatically update from the initialize (reset) file.

Should the method in (2) be utilized, the user can set whether or not to automatically update (change) and the automatic change interval by means of the device display auto change dialog box 824 shown in FIG. 133.

If, in Step S15508, auto change is set then the process proceeds to Step S15509.

If auto change is not set then the flowchart ends.

In Step S15509, NetSpot sets an auto change timer to perform the automatic change. As explained previously in Step S15508, the device display auto change dialog box 824 can be used by the user to set the auto change-interval.

Next, in Step S15510, a check is made as to whether the auto change time set in Step S15509 has now turned off.

If the auto timer has now turned off, then the process returns to Step S15502 for acquisition of information selected again by the current user.

If the auto timer has not turned off, then the process proceeds to Step S15511.

In Step S15511, the user monitors whether auto change has stopped or not. For instance, NetSpot stops the auto change timer when the user switches the sheet display.

If auto change (update) has not stopped, the process returns to Step S15510 and the Steps S15510 and S15511 are repeated.

If auto change has stopped then this flowchart ends.

Also, the flowchart shown in Step S15500 can be implemented as shown in FIG. 157.

Hereafter, Step S15500 is explained based on the flowchart of FIG. 157.

In Step 15701, operation is the same as in Step S15502 however when the sheet information list is not all acquired, then only the move to Step 15702 differs from the operation in Step S15503.

Next, in Step 15702, operation is the same as in Step S15503 however when the previous cache value is retained in the RAM503, the process proceeds to Step S15703 having the same operation as the Step S15501 and when previous cache values are not retained in the RAM503, the process differs by proceeding to Step S15100.

Next, Step S15703 is the same as Step S15501 but when sheet information is acquired, operation proceeds to Step 15100 and if sheet information is not acquired, the process differs by proceeding to Step S15706 having the same operation as Step S15506.

Hereafter, Steps 15704 to Step 15711 are completely the same as Steps S15504 through S15511.

The explanation of this flowchart is now complete.

Implementation of the flowcharts from FIG. 151 through FIG. 157 by NetSpot opens the device list window 701 from the device window 801 to allow switching sheets and displaying various printer information.

Second Embodiment

Hereafter a working example in the second embodiment is given for displaying the device list window 701 from the device window 801 to prevent the user from feeling stress due to delays in operation.

In FIG. 158, the process in the flowchart starts by the user operating the device window for the network management software (NetSpot) during the current start-up.

The NetSpot program executed according to this flowchart is stored in a hard disk (HD) 511. A CPU501 is the main hardware element in running this NetSpot program. However, the main control element for the software is the NetSpot stored in the hard disk (HD) 511. In this embodiment, the operating system (OS) is assumed to be Windows95 (Microsoft Corporation) however the OS is not limited to this.

When the user double-clicks the icons displaying the devices, the device window 701 shown in FIG. 7 is opened in Step S15801. In this step, operation is completely the same as in Step S15201 of the first embodiment.

Next, NetSpot implements Step S15300, the initial sheet information is acquired and displayed on the device window 701.

Next, NetSpot implements Step S15802.

After the initial sheet is displayed, the Step S15802 is for NetSpot to make sheet information sheet for other sheets in order to acquire other sheet information as background.

Next, in Step S15803, determines the sheet to acquire of the sheet information list from among the sheet information lists formed in the above Step S15802.

If restrictions are not placed on the acquisition procedure for sheet information, for instance, if listed in the initialize file or determined at random, then this method will be fixed within the NetSpot program.

Next, Step 15804 and Step 15805 are exactly the same as Steps S15202 and Steps 15203 of the first embodiment so their description is omitted here.

Further, Step 15806 is the same as Step 15204 but when the user has not made entry for another sheet selection, the process differs by proceeding to Step 15807.

Next, in Step S15807, NetSpot checks whether or not acquisition of all information for other sheet information lists formed in Steps S15802 is complete.

If acquisition of all information is complete, the process proceeds to Step S15804 and the process repeats from Step S15804 to S15807 as well as S15400.

If acquisition of all information is not complete, then the process proceeds to Step S15808.

In Step S15808, NetSpot checks whether or not all of the information for the currently acquired sheets if finished.

If the information for the currently acquired sheets is finished, NetSpot proceeds to Step S15809, and the process returns to Step S15803 after the sheet information acquisition end flag was raised.

If the information for the currently acquired sheets is not finished, then NetSpot acquires the printer information by means of Step S15100 and then returns to Step S15804.

The above flowchart process is now complete.

By implementing the above process in the flowchart of FIG. 158, NetSpot was able to open the device window 701 from the device list window 801, switch the sheets, and display a variety of printer information.

Hereafter, the detailed functions of the device window are related.

The contents shown in the device window (FIG. 43) differ according to the device model. Also, the contents shown in the device window (FIG. 43) differ according to the controller mode or the general user mode. Basically, the general user mode is limited in display items and changeable items compared to the controller mode. When an item or function cannot be supported due to the target model or mode being started or network protocol being used: then the screen is conFIG.d with one of the following techniques.

(1) When item is grayed-out and display is invalid or not possible of being changed (basically there is a possibility the item is valid.)

(2) The item itself cannot be displayed (when basically there is no possibility item is valid.)

(3) When the sheet itself of the device window (FIG. 43) is grayed-out and display is invalid or cannot be selected (When a particular tab does not support all items and basically there is a possibility the item is valid.)

(4) When the sheet itself of the device window (FIG. 43) will not display (When a particular tab does not support all items and basically there is no possibility the item is valid.)

In controller registration onto the manager information table and time is required for registering the controller onto the manager information table for the device selected by the user; then the message in FIG. 44 appears and the fact that the controller is currently being registered is reported to the user.

When canceling controller registration onto the manager information table, and time is required for canceling controller registration on the manager information table for the device selected by the user; then the message in FIG. 45 appears and the fact that the controller registration is currently being canceled is reported to the user.

In cases where first displaying a sheet—dialog box on the device window (FIG. 43), and time is required for acquiring information from the device selected by the user, then the fact that information is currently being acquired is reported to the user and when information acquisition is capable of being canceled, the [STOP] is valid.

When time is required for setting information to the device selected by the user, in sheet—dialog box on the device window (FIG. 43), then the message in FIG. 47 appears and the fact that information is currently being set is reported to the user. When this setting of information can be canceled, the [STOP] is valid.

Further, during reset of the printer or reset of the network interface board, and time is required for reset of the device selected by the user, the message in FIG. 48 appears and the user is informed that reset is in progress. When implementing commands other than printer reset or network interface board reset and time is required for implementing commands for devices selected by the user such as printer online-off-line, paper eject, printer initialize, network interface board initialize and various utility commands, then the message in FIG. 49 appears and the user informed that the commands are currently being implemented.

[Device Password Entry Dialog Box (See FIG. 50)]

When the device window is opened (FIG. 43) and the conditions below have been satisfied, the Device Password Entry Dialog Box shown in FIG. 50 is displayed.

[Error Popup Window (See FIG. 142)]

When an error occurs in the device opened in the device window (FIG. 43), an Error Popup Window is displayed in FIG. 142 to show an error has occurred. A detailed message relating to the error that occurred is given in the Error Information Dialog Box (FIG. 55). Error restore operations such as error skip can be performed when the user selects the button on the dialog box.

However, when an error occurs in a device not opened in the device window (FIG. 43), the error is shown with an icon in the device window (FIG. 15). The Error Popup Window (FIG. 142) performs the functions shown in Table 18. TABLE 18 List of functions supported by error popup window ITEM NO. FUNCTION Admin User 1 Report on error that occurred in device ◯ ◯ Display error popup window showing device error Sound a beep tone

When an error occurs in a device opened on the Device Window (FIG. 43) by the menu of the Device List Window (FIG. 15), the user can select whether to display an error popup window or to sound a beep tone.

This function is implemented by using the SNMP trap message. The name of the device in which the error occurred is specified as a NetSpot address for use as a transmit destination address in NetSpot controller mode and a Trap message sent. Therefore, in general user mode in NetSpot the error popup window may sometimes not occur due to the positional relation between NetSpot general user mode and the device on the network.

MIB Data Read-out Method

The MIB data read-out method in the network printer management software of this embodiment is next explained while referring to the flowchart shown in FIG. 161.

The start of MIB data read-out is shown in Step S16100.

An MIB data read-out request is made by the network printer management software to the SNMP agent on the network printer in Step S16101. This MIB data read-out request utilizes the GetRequest-PDU (Protocol Data Unit) and the GetNextRequest-PDU (see RFC 1157). The assembly of these PDUs is performed by an MIB module 610 in FIG. 6 and afterwards an SNMP module 611 performs coding conforming to the SNMP transmit format.

Next, in Step S16102, a read-out report on the MIB data that was requested by the SNMP agent on the network printer to the network printer management software. The MIB data read-out report is utilized by the GetResponse-PDU (See RFC 1157). This GetResponse-PDU includes the MIB data read-out values. This GetResponse-PDU is analyzed by the MIB module 610 after decoding by the SNMP module 611.

Next in Step S16103, utilizing the MIB data reported in Step S16102, the cache values of the MIB data stored in an MIB data cache D15201 are changed. Here, the MIB data cache D16101 is maintained in part of the data storage zones of RAM503 or the hard disk (HD) 511 as shown in the hardware structure in FIG. 5.

The process of FIG. 161 then ends in Step S16104.

MIB Data Write Method

The MIB data write method in the network printer management software of this embodiment is next explained while referring to the flowchart shown in FIG. 162.

The start of MIB data read-out is shown in Step S16200.

In Step 16201, whether to compare the MIB write-specified data values with the MIB data cache values is determined. The reason this step is needed is that some items are essential for writing while some read-out values have little significance so that a comparison of this MIB data with cache value may not be useful.

In Step S16201, when determined that the write-specified MIB data values should be compared against the MIB data cache values, the process proceeds to Step S16202. Conversely, the process proceeds to Step S16204 when determined these two data types should not be compared.

In Step 16202, the MIB data cache values matching the write-specified MIB data, are read-out from the data cache D16201.

Then in Step S16203, the MIB data cache values are compared against the write-specified MIB data values and when determined that these values are not equivalent, the process proceeds to Step S16204. Conversely, when determined that these values are equivalent, the process proceeds to Step S16207 and the process of FIG. 162 then ends.

In Step 16204, an MIB data write request is made to the SNMP agent on the network from the network printer management software. This MIB data write request utilizes SetRequest-PDU (See RFC 1157). An MIB module 610 shown in FIG. 6 arranges this Set-Request-PDU and afterwards, an SNMP module 611 performs coding in conformance with the SNMP transmit format.

Next, in Step S16205, an MIB data write report request is made from the SNMP agent on the network to the network printer management software. This MIB data write report utilizes Get-Response-PDU (See RFC 1157). This Get-Response-PDU includes written MIB data values. This Get-Response-PDU is analyzed by the MIB module 610 after decoding by an SNMP module 611.

In the subsequent Step S15306, the MIB data cache values stored in the cache D15201 (See description for FIG. 161) of the MIB data are changed by utilizing the MIB data reported in Step 16205.

Then in Step 16207, the process of FIG. 162 then ends.

The above process, functions on network controlled equipment. Consequently, the cache memory is held in common by the entire network.

In this embodiment therefore, as explained above, a step is provided in network printer management software utilizing SNMP protocol, to distinguish between MIB data requiring a write request and MIB data not requiring a write request for an SNMP agent in a network printer from among MIB data corresponding to user write-specified information; so that write requests for MIB data not required by the SNMP agent on the network printer are therefore not performed. Consequently, the above process allows the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

Further, by providing a step to store in the MIB data cache, MIB data obtained in the MIB data read-out process and a step to compare MIB data in the MIB write process matching write-specified information from the user against the MIB data stored in the cache in the previous step; the MIB data requiring a write request can be distinguished from MIB data not requiring a write request for an SNMP agent in a network printer from among MIB data corresponding to user write-specified information, and write requests will therefore not be made for MIB data not required by the SNMP agent on the network printer. Accordingly, the above process allows the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

Alternatively, by providing a step to store in the MIB data cache, written MIB data obtained in the MIB data write process and a step to compare MIB data of the MIB write process matching write-specified information from the user against the MIB data store in the cache in the previous step; the MIB data requiring a write request can be distinguished from MIB data not requiring a write request for an SNMP agent in a network printer from among MIB data corresponding to user write-specified information, and write requests will therefore not be made for MIB data not required by the SNMP agent on the network printer. Accordingly, the above process allows the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

Still further, by providing a step to store in the MIB data cache, MIB data obtained in the MIB data read-out process and a step to store MIB data written in the write process into the MIB data cache, along with a step to compare MIB data of the MIB write process that matches write-specified information from the user against the MIB data stored in the cache in either of the previous steps; the MIB data requiring a write request can be distinguished from MIB data not requiring a write request for an SNMP agent in a network printer from among MIB data corresponding to user write-specified information, and write requests will therefore not be made for MIB data not required by the SNMP agent on the network printer. Accordingly, the above process allows the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

In this invention therefore, as explained above, not all MIB objects under the control of the network management software are acquired simultaneously during startup of the network management software. Consequently, the flow of a large volume of SNMP packets in the LAN will cease and along with a simultaneous reduction in load on channels, the load on the devices such as the printer and network board controlling that process these SNMP packets will become small.

Further by providing a network data base control device and method that creates only a small load on the LAN, printer and network boards, the time required to start up (display initial menu) the network management software will be drastically shortened and the user will thus be provided with an easier operating environment.

Also, in network printer management software utilizing SNMP protocol, there will be no processing of change or write requests for unneeded MIB data, while write requests for necessary MIB data for SNMP agents of the device (such as printers) on the network matching write-specified information from the user will be processed, thus allowing the amount of network traffic (data flow rate) and the load (amount of work) applied to the network printer to be reduced.

As many apparently widely different embodiments of the present invention can be made without departing from the spirit and scope of the present invention, it is understood that this invention is not limited to the specific embodiments thereof except as defined in the appended claims.
